B-12 Chemtool versus SeaFoam

I am curious if the B-12 can be used to SeaFoam a vehicle. What I am referring to is the vacuumn line trick where you pour half the can into the brake booster line to clean the intake out... SeaFoam has brought carbs on small engines back from the dead for me. I was given a riding mower that was neglected. The oil had not been changed in along time, and adding SeaFoam to the crankcase drained the oil looking like tar, but the motor has been running strong now for the last several years. You can catch it onsale for $7 a can, then I will usually pick up 3 or 4 then.
